LOCKlNG DEVl-CE FOR THE OPERATING-CRANKS 0F CASH-REGISTERS.

SEEGIFICATION forming part of Letters Patent N o. 707,603, dated August26, 1902. Application filed (lune 5, 1900. Serial No. 19,094. (Nomodel.)

.To @Z5 'zu/tant it may concern.-

Beit known thatLGARLLAURICK, a subject `of the King of Prussia, GermanEmperor, and

a resident of Berlin, in the Kingdom of Prus sia and Empire of Germany,have invented certain new and useful Improvements in Devices for Lockingthe Operating-@ranks of Cash-Registers, of which the following is aspecification.

The object of the invention is to provide means for preventing theturning of the operating-crank of a cash-register until the salesman oroperatorhas deposited within the cashregister a ticket indicating hisname, number, or the like.

The invention is illustrated in the accompanying drawings, in which-,:Figure 1 is a vertical longitudinal section of a portion of acash-register casing,sho win g the application of the invention. Fig. 2isaplan view of the same. Fig. `3 is a sectional detail.

In the drawings, A indicates a portion of the casing of a cash-registerwhich is deemed sufficient for illustrating the present invention. Anoperating crank or handle is indicated at 1G, which is connected to andturns upon an operating-shaft 14. An arm 20 is carried by this shaft andin the normal position of the parts depends into the position shown inFig. 1, where it is provided with a pin 120, which is engaged by thehooked end of a locking-arm 1S, pivotally secured to any iixed pointwithin the casing. As long as this hooked arm is in engagement with thepin the crank of the register is locked against movement. In. order todisengage the arm 18 from the pin, I provide a rocking lever 129,carrying at its rear end a pawl 130, having a hooked portion engagingthe hooked end of the arm 1S. The forward end of lthe lever 129 isdesigned to be operated by the slide mechanism hereinafter described.

A slide 23 is suitably guided in the walls of the casing and has in itsupper surface a recess to receive a suitable ticket (indicated at 2l)which may be inserted through an opening 22 in the projecting portion ofthe casing. This slide tends to move toward the rear by the tension of aspring in the manner-hereinafter described. Aretaining-lever 121 ispivoted to a lug or projection 121 on the under part of the slide, andthe lever is provided on its front end with a hook or catch designed toengage with the edge of the casing to thus lock the slide againstrearward movement. The catch isheldin engagement with the casing by aspring 133, and the projecting portion 133 serves as a handle for thedepression of the front end of the lever. In order to hold the lever 121against movement except when the ticket has been inserted, I provide atransverse rock-shaft 29, which has a plurality -of depending fingers 30extending down into the path ot' the ticket and also other fingers orprojections 31, designed to engage the rear end of the lever 121,asshown in Fig. 1. lVhen, however, the ticket 21 is inserted and shovedrearwardly, the impact of the ticket against the iin gers 30 causes theprojections 31 to be moved out of contactwith the rear end of the lever121, which may then be depressed to release the slide. A supplementalslide 125 is suitably guided in the casing and is under the tension of aspring 122, connected to a pin 132 and tending to draw said slide 125toward the rear. A pin 134:, carried by the slide 125, engages the frontside of a stop 124 when ,the slide 125 moves rearwardly, and thus tendsto carry the slide 23 back with it. The slide 125 has a projection 128,which engages the forward end of the lever 129 when the slide nears thelimit of its backward movement, and thus releases the pin 120 from thearm 18 in the manner hereinbefore described. In order that the slide 23may be restored to initial position, the cash-drawer (not shown) may becaused to engage the pin 132 when it is drawn out, and thus carry theslide 125 with it. A pawl 126 is pivotally connected to the slide 125and has one edge adapted to slide upon the lower edge 127 of the guide,thus holding its upper edge or nose in contact with the rear side of thestop 124C until the slide 23 has been drawn forward suiiiciently toallow the catch on the lever 121 to engage the edge ol the casing. Vhenthis point is reached, the lower edge of the pawl 126 reaches thecut-away portion 127, which permits the pawl to rock backward, asindicated in dotted lines, to clear the projection 124 and thecash-drawer to continue its outward movement without affecting the slide23. On the reverse movement of the cash- IOO drawer the pawl will rockin the opposite direction and the slide 125 moves backward under thetension ofthe spring until the lower edge of the pawl engages the edge127 of the: guide and the pin 134 comes in contact with A glass 123permits of the inspection of thev ticket when it has been carriedrearwardly by the slide.

From the foregoing description the operation of the device will beclear, but may be briefiy stated as follows: The crank 16 of thecash-register is normally held against movement, as indicated in Fig. 1.Thefsalesman who desires to operate the cash-register inserts a ticketthrough the opening 22 and pushes it rearwardly until it swings theprojections 31 out of engagement with the lever 121. The operator thendepresses the end `1332*, to be drawn rearwardlyy under the action ofthe spring 122, slides 23 and 125 moving rearwardly together. As soon asthe slide 125 nears the limit of its backward movement the projection128 contacts with the forward end of the arm 129 and raises the pawl130, and with it the arm 18, thus freeing the arm 2O and allowing thecash-register handle to be operated. The cash-register may now beoperated in the usual manner. In order to prevent a double rotation ofthe handle without the slides having been moved forward by the openingof the cash-drawer, a pawl 131 is pivoted to the arm 20, and which asthe arm 2O nears its initial movement engages the pawl y130 and rocks itto disengage it from the end of the arm 18, allowing the end of said armto drop into engagement with the pin 120.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination with the operatingcrank of a cash-register, of alocking device for holding the same against movement, a slide forreleasing said locking device, a spring tending to retract said slid e,means for holding the slide normally advanced, and check-controlledmeans for releasing said holding means, substantially as described.
